2 Claims.

This invention relates to fastening devices and particularly to fastening devices for the mounting of plates such as glass plates and the like.

Instruments or devices requiring the mounting of a plate, for instance, of a glass over a Window usually provide a snap ring or a system of clamps for retaining the glass in place. devices have the disadvantage that they require tools for their assembly and disassembly. When vantage if the window framejs made of a soft metal or a plastic such as Bakelite. Snap rings are further limited in their use to the mounting of circular glasses and cannot readily be adapted to odd shaped glasses.

An object of the invention is the provision of means by which a plate of glass or other suitable material can be fastened on or removed from the window frame by hand and without the use of tools.

Another object of the invention is the provision of means by which a plate with any irregular contour can be conveniently fastened on the window frame.

Further and other objects and advantages of the invention will be hereinafter set forth and other features thereof will be pointed out in the appended claims.

According to a now preferred embodiment of the invention, one or more spring clips are provided which engage a suitable slot on the member on which it is desired to mount the glass. These clips can be readily fastened and removed by hand and without the use of tools. of these clips may be applied to the fastening of a glass with any irregular contour.

A better understanding of the invention will be afforded by the following detailed description in connection with the accompanying drawings, in which Fig. 1 is a plan view showing an embodiment of the invention applied to the mounting of a glass on a rectangular window;

Fig. 2 is a detail view substantially in perspective of the clip assembly taken along line 22 of Fig. 1;

Fig. 3 is a detail of the clip used in Fig. 2;

Fig. 4 is a perspective view of a modification shown applied to a non-linear glass. and

Fig. 5 is a detail of the clip used in Fig. 4.

The same reference characters are used throughout the drawings to designate like parts.

Fig. 1 illustrates a window frame II, having Serial No. 579,533

(Cl. Zeb-259) at right angles to extensions is to be covered by glass I3.

Mounted on frame as may better be seen from Fig. 2. These bosses may be permanently mounted by staking, welding, soldering, riveting or any other suitable method. In some cases where the window frame is a casting, boss I 4 may be an integral part of the casting as shown on Fig. 4. Bosses III are mounted to line up with the edge of the glass as shown. Each boss I4 is provided with two slots I1. Coacting with each boss is a clip I5 which is shown in greater detail in Fig. 3. Clip I5 is formed by a strip of a material having a reasonable flexibility such as metal. The clip is provided with two extensions I8, preferably near the center of the strip. These extensions are made to fit in slots I! of boss I4. At either end of clip I5 are two ears I9 extending downward and I8. These ears serve to engage the glass at the edge as better shown in Fig. 2 and lock the clip in place.

In assembling the window frame, the glass I3 is first laid on the frame II between bosses I4. If desired, a gasket 20 may be used. The clips are mounted by flexing the clip and inserting the two extensions I8 into the slots of boss I4 until ears l9 click over the edge of the glass. This procedure is repeated for as many clips as are required in the particular assembly. Once the ears I9 have slipped over the edge of the glass, it will normally be impossible to push the clip out again, since the two ears prevent the clip the length of the strip is prevented by the engagement of the extensions I8 in the slots I! of boss I4. Since the clip I5 has spring properties, and is flexed in assembly, it glass and hold it firmly assembled to the window frame. If desired, a number of bosses I 6 may be provided to position the glass further.

When it is desired to remove the glass, the clip may be removed, merely by flexing the two ears I9 at the end of the clip I5 up until they clear the glass. When the ears are in this position, the extensions I8 may readily he slipped out of Fig. 4 illustrates a modification of the invention in application to a circular glass plate. According to Fig. 4, the window frame IIa itself is provided with a single slot 2|. The clip 22 is similar to that described in connection with Fig. 3 with the exception that a single extension 23 is provided as better shown in Fig. 5 which is slightly bent to'give it spring properties. In assembly, Fig. 4, extension 23 is first inserted into slot 2| of window frame I la, and pushed in until the ears [9a, which are the same in construction and function as the similarly numbered parts in the form shown in Figs. 1 to 3, click over the edge of glass 24. When in this operative "position, the ears l9a extend between the frame Na and the edge of the glass, thereby preventing the clip from backing out; and sidewise motion is prevented by the engagement of extension 23 in slot 2|. Since the clip is assembled under tension, i. e. in a flexed condition, the glass will be held firmly against the window.

While the clip with two extension arms l1 has been shown in connection with the assembly of a straight glass as shown in Fig. 2, and the clip with a single extension 23 has been shown in connection with the assembly of a non-linear glass, it should be clearly understood either type of clip may be used with glasses of any contour, and that the drawings have been shown by way of illustration and not of limitation. It should further be understood that in connection with the assembly shown in Fig. 4 separate bosses may be provided as shown, for example, at M in Figs. 1 and 2 and that in Fig. 2 the slots I! may be provided in the window frame itself.

What is claimed is:

i. The combination with a frame and a cover to be secured thereto in a predetermined position, said frame having a part rigid therewith adjacent to an edge of the cover at said predetermined position, which part has a slot formed therein extending laterally away from the adjacent edge of said cover, of a clip securing said cover to said frame, said clip comprising an elongate strip of resilient material positioned to extend along said edge, a lateral extension of said strip slidingly received in said slot, cars at portions of said strip remote from said extension, said ears projecting laterally from the main plane of said strip on the same side thereof as said extension and positioned to extend laterally out of the plane of said strip and over the edge of said cover at the operative position of said strip, said slot being disposed at such a position in respect to said cover that when said ears rest on the surface of said cover in moving said clip toward its operative position, said strip must be flexed to permit said lateral extension to be inserted into said slot.

2. The combination in accordance with claim 1, wherein two slots as aforesaid are provided adjacent to one another, and wherein two similar lateral extensions are provided complementary to said slots and coopera'ble therewith as a tongueand-groove connection on movement of said clip to its operative position.
